located on the right side of the meter clus-
ter. The odometer is located within the ve-
hicle information display.

METERS AND GAUGES

CAUTION
When engine speed approaches the
red zone, shif t to a higher gear or re-
duce engine speed. Operating the en-
gine in the red zone may cause serious
engine damage.
ENGINE COOLANT TEMPERATURE
GAUGE
NOTE:
The ignition switch must be placed in the
ON position for the gauge to give a
reading.
The gauge indicates the engine coolant
temperature. The engine coolant tempera-
ture is within the normal range when the
reading is within the zone
OAshown in the
illustration. The engine coolant temperature varies
with the outside air temperature and driv-
ing conditions.
2-6Instruments and controls

Cooling
This mode is used to cool and dehumidif y
the air.
1. Press the
button to the off position.
2. Press the
air flow control button.
3. Turn the
fan speed control dial to
the desired position.
4. Press the A/C button. The indicator light comes on.
5. Turn the temperature control dial to the desired position.
• For quick cooling when the outside tem- perature is high, press the
button to
the ON position. Be sure to return the
to the off position for normal cooling.
MAX A/C may be used for quick cooling.
Dehumidified heating
This mode is used to heat and dehumidif y
the air.
1. Press the
button to the off position.
2. Press the
air flow control button.
3. Turn the
fan speed control dial to
the desired position.
4. Press the A/C (air conditioner) button. The indicator light comes on. 5. Turn the temperature control dial to the
desired position.
Dehumidified defogging
This mode is used to defog the windows
and dehumidif y the air.
1. Press the
air flow control button.
2. Turn the
fan speed control dial to
the desired position.
• When the
orare selected, the
air conditioner automatically turns on if
the outside temperature is more than
36°F (2°C). This dehumidifies the air which
helps defog the windshield. The
mode automatically turns off, allowing
outside air to be drawn into the passen-
ger compartment to further improve the
defogging performance.
3. Turn the temperature control dial to the desired position.
Operating tips
• Keep the windows closed while the airconditioner is in operation. • Af ter parking in the sun, drive for 2 or 3
minutes with the windows open to vent
hot air from the passenger compart-
ment. Then, close the windows. This al-
lows the air conditioner to cool the inte-
rior more quickly.
• The air conditioning system should be operated for approximately 10 minutes at
least once a month. This helps prevent
damage to the system due to lack of lu-
brication.
• A visible mist may be seen coming from the ventilators in hot, humid conditions
as the air is cooled rapidly. This does not
indicate a malfunction.
• If the engine coolant temperature gauge indicates engine coolant temperature
over the normal range, turn the air condi-
tioner off. For additional information, refer
to “If your vehicle overheats” in the “In case
of emergency” section of this manual.
• When Remote Engine Start (if so equipped) is activated, the manual cli-
mate control system will default to the
last used heating or cooling mode.
4-36Monitor, climate, audio, phone and voice recognition systems

• When the climate system is in automaticoperation and the engine coolant tem-
perature and outside air temperature are
low, the air flow outlet may default to de-
froster mode for a maximum of 2 min-
utes 30 seconds. This is not a malfunc-
tion. Af ter the engine coolant
temperature warms up, the air flow outlet
will return to foot mode and operation will
continue normally.
• When the outside and interior cabin tem- peratures are moderate to high, the in-
take setting may default to turn off air
recirculation to allow fresh air into the
passenger compartment. You may no-
tice air flow from the foot mode, bi-level
mode, or side demist vent outlets for a
maximum of 15 seconds. This may occur
when the previous climate setting was
turned off. This is not a malfunction. Af ter
the initial warm air is expelled, the intake
will return to automatic control, the air
flow outlet will return to previous settings,
and operation will continue normally. To
exit, press any climate control button.
• Keep the moonroof (if so equipped) closed while the air conditioner is in op-
eration. • If you feel that the air flow mode you have
selected and the outlets the air is coming
out do not match, select the
mode.
• When you change the air flow mode, you may feel air flow from the foot outlets for
just a moment. This is not a malfunction. The air conditioner system in your NISSAN
vehicle is charged with a refrigerant de-
signed with the environment in mind.
This refrigerant does not harm the
earth's ozone layer.
Special charging equipment and lubricant
is required when servicing your NISSAN air
conditioner. Using improper refrigerants or
lubricants will cause severe damage to
your air conditioner system. For additional
information, refer to “Air conditioner sys-
tem refrigerant and oil recommendations”
in the “Technical and consumer informa-
tion” section of this manual.
It is recommended that you visit a NISSAN
dealer to service your “environmentally
friendly ” air conditioning system.
